From 736532a0705ffc27c14f712fa2758a7f8b15e8b4 Mon Sep 17 00:00:00 2001 From: "Karicheri, Muralidharan" Date: Wed, 23 Sep 2015 13:37:07 -0400 Subject: [PATCH] net: netcp: move netcp_register_interface() to after attach module The netcp interface is not fully initialized before attach the module to the interface. For example, the tx pipe/rx pipe is initialized in ethss module as part of attach(). So until this is complete, the interface can't be registered. So move registration of interface to net device outside the current loop that attaches the modules to the interface. Signed-off-by: Murali Karicheri Signed-off-by: David S.
